Component documentationSAP TDMS Application Overview

 

SAP Test Data Migration Server is a high-speed data extraction tool that transfers relevant business data from your SAP production system to your development, test, quality assurance, or training system.

By enabling the transfer of just the relevant set of application data from the SAP production system, SAP TDMS allows you to create a lean and consistent non-production system.

SAP TDMS can be used in the test phase of SAP Application Lifecycle Management.

Implementation Considerations

  • You have installed the DMIS 2011 and DMIS_CNT 2011 Add-On components in the sender system, receiver system, and the central system in the SAP TDMS landscape.

  • You have configured the central system to run on SAP NetWeaver 7.0x or above.

  • You have configured the sender system and the receiver system to run on WebAS 620 or above.

Additional Considerations

  • The selection of the migration solution depends on the data requirement in the non-production landscape.

    Example Example

    The non-production landscape is intended for use as a training system for the SAP Sales and Distribution module. You select the BPL-Based Transfer migration solution to migrate specific sales orders.

    End of the example.

  • The definition of migration parameters relevant to the migration solution depends on the business requirements of the non-production landscape.

    Example Example

    There are discrepancies in the employee data of an organizational unit. The HCM user migrates data relevant to all employees in that organizational unit to the test system to carry out a data analysis.

    End of the example.

Integration

Integration with Snapshot Technology

With SAP TDMS you can use third-party tools that enable the creation of database snapshots. The database snapshot replicates the production system and can be used as the sender system in the TDMS landscape. Data extraction from the snapshot system ensures the following benefits:

  • Maximum data consistency during data transfer

  • Minimum performance load on the production system during a TDMS run

For more information about integration with snapshot technology, see the relevant how-to guide for TDMS 4.0 on the SAP Service Marketplace at http://service.sap/com/instguidesInformation published on non-SAP site.

Features

Data Transfer Criteria

You can select production data relevant for transfer based on time, organizational unit, or business processes. You can choose to replace all existing application data in a client or augment the data in an existing client with additional data specific to the business processes.

Data Privacy

You can choose to scramble sensitive data before data migration by using the scrambling content provided by SAP or by creating custom scrambling rules.

Data Consistency

SAP TDMS provides a number of features to provide a high-level of data consistency in your non-production systems.

When extracting the data belonging to a specific time slice, for example, SAP TDMS extracts data from business documents created in that time slice along with data from related documents outside the time slice. Hence, the data in a business process flow is transferred to the receiver system to allow for a high degree of data consistency.

For more information about data consistency, see the Operations Guide for SAP TDMS 4.0 on the SAP Service Marketplace at http://service.sap/com/instguidesInformation published on non-SAP site.

System Shell Creation

You can use the system shell creation feature to create a fresh non-production system by copying the repository definitions and the cross-client customizing from the production system. The non-production system generated by this method does not contain any application data. After the system shell creation process, you can transfer the relevant application data using SAP TDMS.

Relevant Applications

SAP TDMS is available for following applications:

  • SAP ERP Central Component

  • SAP Business Warehouse

  • SAP Business Suite: SAP Human Capital Management, SAP Customer Relationship Management, SAP Supply Chain Management, and SAP Supplier Relationship Management

  • SAP for Industries: Utilities, Banking, Retail, Apparel and Footwear Solution, Discrete Industries and Mill Products, Oil and Gas (Downstream) and Healthcare

Migration Solutions

SAP TDMS provides the following migration solutions:

  • Time-Based Reduction: Transfers all client-specific application data within a specified time slice from the production client to a specified client in the non-production system.

  • Transfer of Master Data and Customizing: Transfers client-specific master data and customizing data, but not the transactional data, from the production client to a specified client in the non-production system.

  • Company Code and Time-Based Reduction: Transfers data belonging to specified company codes and residing in a specified time slice from the production client to a specified client in the non-production system.

  • Full Transfer of Client-Specific Data: Transfers all client-specific application data from the production client to a specified client in the non-production system.

  • Business Process Library: Transfers data specific to a business process such as sales order from the ERP production client to any client in the non-production system. You use this migration solution if you want to you want to add business process data to (or modify business process data in) the data in your current non-production system.

  • Transfer of Human Capital Management Data:Transfers SAP ERP HCM data, which has been filtered based on your business criteria, from the production system to the non-production system.

  • Data Import Through Files: Allows the export of data to a file before importing the file to the receiver system using the File Transfer Protocol or a disk.

  • Object-Based Reduction for Industries: Transfers data specific to business objects such as business partners, contracts, stores, or external accounts from the production system to the non-production system. You use this migration solution if you want to completely wipe out the data in the non-production client and carry out a mass transfer of business object data.

  • System Shell Creation: Copies repository information and cross-client Customizing from the production system to a new non-production system. The new non-production system does not contain any application data. You can use a relevant migration solution to transfer application-related data.

  • Stand-Alone Scrambling: Allows the scrambling of sensitive data residing in a particular non-production system without transferring data across systems.
